Its interesting to think about the history of bbq. I think we can all agree that "real" bbq involves smoking the meat. Anything else is just grilling. i.e. Argentina, Greece, Italy.
BBQ comes from the native Caribbean Indian word Barabicu. This was a method of salting and smoking meat and fish to preserve. As the story goes the natives showed the British Buccaneers how to do it. Then they would salt and smoke feral pigs and what not from the islands then take them back to the ships for voyages.
The method was four branches as legs with a grill top of wood with all the meat tied to it. Then it was raised high off of the coals and would be smoked open air style.
I think if you long cold smoke it and then finish it hot before serving you will be experiencing bbq in its pristine state.
